Adding Functionality to Detail View

Is there any way to do this? I’ve tried creating Buttons and Links in the associated Grid Application, but I cannot get anything to appear in the toolbar options for the detail view.

Assuming it is not possible to add anything to the detail view, is there any way to customize the PDF that is generated by the detail view? I’ve watched the videos on PDF customization, but they appear to pertain only to creating a PDF output application.
